The two arms, the spindle, and the body, form a four-bar link.Use of the linkage at the lower suspension connection of either a MacPherson strut or a short long arms suspension readily gives an effective virtual ball joint outboard of the spindle, which is very useful for a suspension designer, allowing negative scrub radius whilst allowing the ball joints to move in and thus out of the way of ...
The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front ...
MacPherson strut/Chapman strut; Upper and lower A-arm (double wishbone) Multi-link suspension; Semi-trailing arm suspension; Swinging arm Transverse leaf springs when used as a suspension link, or four-quarter elliptics on one end of a car are similar to wishbones in geometry, but are more compliant.
Double wishbone suspensions are more complex, impose more difficult packaging constraints, and are thus often more expensive than other systems like a MacPherson strut. Due to the increased number of components within the suspension setup, it takes much longer to service and is heavier than an equivalent MacPherson design.
Dual-pivot steering geometry (also known as virtual pivot) is a geometric arrangement of linkages in the steering of a car designed to reduce or eliminate scrub radius by moving the pivot point of the king pin outboard, in order to improve steering precision and straight line stability.
Texas officials try to intercept sale of surplus border wall materials Patrick noted that Texas became aware of the materials slated for auction on Dec. 12, the same day the Daily Wire reported ...
A strut bar, strut brace, or strut tower brace (STB) is an automotive suspension accessory on a monocoque or unibody chassis to provide extra stiffness between the strut towers. With a MacPherson strut suspension system where the spring and shock absorber combine in one suspension unit, which also replaces the upper control arm, the entire ...
Earle Steele MacPherson (July 6, 1891 – January 26, 1960) was an American automotive engineer, most famous for developing the MacPherson strut in the 1940s. Biography [ edit ]
